Toshiba Releases Medium Voltage, High Current Photorelay in Small Package
02.21.2018 · News
Toshiba Electronics Europe has announced the launch of a new photorelay in a small 2.54SOP4 package that is just 2.1 mm high with a 2.54 mm pitch. Fabricated using the latest U-MOS VIII trench MOSFET process, the new TLP3145 combines an off-state output terminal voltage of 200 V with a controllable on-state current of up to 0.4 A continuously or 1.2 A when pulsed...
Supercapacitor-Based Power Backup Prevents Data Loss in RAID Systems
Supercapacitor-Based Power Backup Prevents Data Loss in RAID Systems
02.20.2018 · Circuits
Redundant arrays of independent disks, or RAID, systems, by nature are designed to preserve data in the face of adverse circumstances. One example is power failure, thereby threatening data that is temporarily stored in volatile memory. To protect this data, many systems incorporate a battery-based power backup that supplies short-term power – enough watt-seconds for the RAID controller to write volatile data to nonvolatile memory...

Microprocessor Supervisory Circuit from Diodes Incorporated Monitors System Voltage with Programmable Delay
02.19.2018 · News
Diodes Incorporated announced the PT7M3808 family of microprocessor supervisory circuits. These devices monitor system voltages from 0.4 V to 5.0 V, and feature threshold accuracy from 0.5% and an adjustable delay time from 1.25 ms to 10 ms...
Use two PicoGate devices for bidirectional level-shifting
Use two PicoGate devices for bidirectional level-shifting
02.16.2018 · Circuits
In new mixed-voltage systems, it is often necessary to level-shift a control signal from a high level to a low level. An open-drain device, such as the 74LVC2G07, easily performs this shift. However, when a bidirectional signal requires level-shifting, it takes a bit more circuitry...
